Temperatures will reach the 70s again today and Thursday, before much cooler weather arrives to start the weekend. Areas of frost are still likely; while prospects of a widespread freeze do not appear as high as they did earlier, a few locations are still prone to dip below freezing, mainly northwest of I-55. Rain-wise, scattered showers will move across the region late this afternoon and into tonight, though amounts will generally be less than a tenth of an inch, before dry weather returns for Thursday into the weekend.
